From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Borislav Petkov To: linux-stable Cc: Greg Kroah-Hartman , X86-ML , LKML Subject: [PATCH 4/4] x86-32, amd: Move va_align definition to unbreak 32-bit build Date: Fri, 4 Nov 2011 12:15:54 +0100 Message-Id: <1320405354-9850-4-git-send-email-bp@amd64.org> In-Reply-To: <1320405354-9850-1-git-send-email-bp@amd64.org> References: <20111104111115.GA8020@aftab> <1320405354-9850-1-git-send-email-bp@amd64.org> Sender: linux-kernel-owner@vger.kernel.org List-ID: From: Borislav Petkov Upstream commit: 9387f774d61b01ab71bade85e6d0bfab0b3419bd hpa reported that dfb09f9b7ab03fd367740e541a5caf830ed56726 breaks 32-bit builds with the following error message: /home/hpa/kernel/linux-tip.cpu/arch/x86/kernel/cpu/amd.c:437: undefined reference to `va_align' /home/hpa/kernel/linux-tip.cpu/arch/x86/kernel/cpu/amd.c:436: undefined reference to `va_align' This is due to the fact that va_align is a global in a 64-bit only compilation unit. Move it to mmap.c where it is visible to both subarches. Signed-off-by: Borislav Petkov Link: http://lkml.kernel.org/r/1312633899-1131-1-git-send-email-bp@amd64.org Signed-off-by: H.
